Commercial & Industrial

We can also work with you to design a preventative maintenance programme for your existing (or new) HVAC system, ensuring that it is always running in a safe and energy efficient manner – keeping your office or plant at the right temperature, heading off costly, inconvenient or dangerous breakdowns and keeping your customers and staff happy!

Our expertise means we can also design and install specialised HVAC systems for industrial sites, such as ventilation tunnels for mining. Talk to us about your requirements.


HVAC stands for Heating, Ventilation, and Air Conditioning. HVAC refers to the different systems used for moving air between indoor and outdoor areas, along with heating and cooling both residential and commercial buildings. They are the systems that keep you warm and cosy in the winter and feeling cool and fresh in the summer. They also are the systems that filter and clean indoor air to keep you healthy and maintain humidity levels at optimal comfort levels. 

Each component in your home may be separate, such as a radiant system combined with window air conditioning units. However, it is more common for combined systems such as central heating and AC systems that use a single blower to circulate air via internal ducts in a home, or with a ductless system for different rooms or zones in the house.

The purpose of an HVAC system is more than just warming or cooling a space. Instead, it serves to improve indoor air quality and provide comfort for everyone inside a building. While there are several different types of HVAC systems, they all begin with the same essentials.First, there is a source of fresh air intake from the outside or from within the home. This process is called ventilation, and it happens in two different ways. Natural ventilation is present in most homes and refers to the way air typically moves in and out through windows, doors, vents, and other openings. This exchange of air is necessary to replenish oxygen, and to remove odours, carbon dioxide, unpleasant odours, and excessive moisture. Mechanical ventilation uses a mechanical system to move air in and out. Once the air is brought in, it is drawn into an air handling unit where the work begins. Here, air is drawn through filters to remove dirt, dust, allergens, and other particles. Next up is comfort. Air is either sent to be heated or sent to be cooled and have excess humidity removed. Once the air is clean, fresh, and at a comfortable temperature, it is directed into the home. For central systems, this means moving through a network of ducts and registers to different rooms. For other systems, this usually means being directed right into the space.

You can avoid costly HVAC repairs by having your system regularly inspected and maintained by one of our certified technicians. Find your local Aotea technician.
